The show stopper for me was when one of my working camera video feeds quit working within E+. It worked and then it didn't work. Browser & VLC interface showed functioning cam. Another pain is glacial performance which I could live with but is no joy. Running on a Win 2012 Server with 4 core / 8 thread haswell xeon which is not the fastest setup but still no slouch. Overall Essential+ R2 appears beta phase at best to me. After 3 days of trying to wrestle E+ into submission, I threw in the towel.
